b18a swap

hey guys im pretty new to the honda scene. i have a 97 integra ls. im wanting to build a ls/vtec turbo to drop into my car. i found a b18a motor i can get for free, so im asking if the b18a motor will drop right into my 97 with a b18b? how much work would it be and is it worth while or should i be looking for anoth b18b1? thx in advance

i have the same plans for my 96 i jsut dropped the engine that was in that into my 91 and have a low mileage b15c1 block to use for the ls vtec, all B series heads and blocks are dimensionally the same its the internal shit and the brackets and external shit that are different.

B18a/b is the same engine, just different intake manifolds, B18b has slightly hotter cams(maybe) and different ecu control. Provided you use the 94-00 intake manifold and injector setup on the B18a then yes its a common sense swap. The B18a doesnt have a provision for the knock sensor on the back but you can rig it up to work in another empty hole on the engine.
